EVALUATING FOREST VOLUME ESTIMATION AT BARKSDALE AIR FORCE BASE USING LIDAR AND MULTISPECTRAL IMAGERY

摘要

Hardwood and pine stand volume estimates compiled from past field plot samples were compared to Lidar volume estimates through the interpretation of Lidar assessed height, crown width and trees per acre to ascertain if Lidar derived volume estimates can be used in lieu of traditional volume measurements. Initially, a map representing all hardwood and pine forest stands at Barksdale Air Force Base, Louisiana were extracted from a map encompassing the entire base. Once extracted, sample points for allpine stands were determined to mimic the sampling density of already existing sampling points for hardwood forest volume estimates on the base (Figure 1). Once determined, field crews visited each pine stand sample point to assess pine volume estimates per acre using 1/1 Oth acre sample plots identified within the pine forest area using traditional field measurements of species, DBH, total height and crown width.
